My research focuses on
I am, first and foremost, a cytogeneticist, pursuing various types of chromosome analyses in an effort to understand plant evolution. My interest in cytogenetic studies encompasses many taxonomic groups, but especially ferns and various genera of the mustard family (Brassicaceae), mostly Boechera and Draba. Targeting taxa and regions that are poorly-known, I aim to develop baseline chromosome data that can then be integrated with other systematic data to test hypotheses of relationship. Implicit in every project is the goal of developing a set of chromosome vouchers to provide DNA samples for phylogenetic studies. Chromosome work on these groups have revealed an incredibly complex pattern of reticulate (hybrid) evolution that cannot be resolved without integrating information from cytogenetics, morphology, molecular systematics and reproductive biology.
Studies such as those outlined above often lead to the discovery of chromosomal variation within taxa that have been accepted as a single species. This is where my interest in population genetics and biogeography come into play. With sufficient sampling of cytogenetic and molecular variability, fascinating geographic patterns often emerge. These patterns can tell us much about the details of evolution and often lead to new hypotheses of relationship.
I am broadly interested in fern phylogenetics, with a focus on the adiantoid clade (Pteridaceae). In particular, I am obsessed with demonstrating the monophyly of Adiantum, and plumbing the complexities of cheilanthoid evolution. I also like Gilligan.
I have broad interest in plant systematics, anatomy, and microscopy.
My current research is focused on the function and evolution of "farina" (waxy flavonoid exudates on leaf surface) in the desiccation-tolerant fern clade notholaenids (Pteridaceae). For more information about my current and previous studies, please visit my website.
I am broadly interested in the Andes as a region, especially how diversification and evolution have occurred in the dry Inter-Andean valleys. I'm keen on understanding biogeographical patterns and the effects that varied reproductive strategies (polyploidy, apomixis, various levels of selfing) have had on diversification.
